Abstract

The invention discloses an energy device single-particle burning pulse measurement system and method, and belongs to the technical field of anti-radiation effect test and reinforcement of energy devices. The system is composed of femtosecond pulse laser equipment, a three-dimensional mobile platform, a probe station, an energy device, a direct current bias power supply, a bias and sampling network and a data acquisition module. By arranging a three-terminal current sampling branch and a drain voltage sampling branch, the system can synchronously acquire multi-parameter transient waveforms under the same trigger. According to the system design, it is ensured that real bias is kept, meanwhile, transient current is prevented from being recharged to the direct-current bias power supply, and therefore the test safety is improved, and high-fidelity transient waveform data are provided. The system has high measurement bandwidth and low distortion, can accurately measure the single-particle burning transient behavior of the energy device, and is suitable for single-particle burning mechanism research and anti-radiation evaluation of multiple types of energy devices.
